Large caliber submersible sewage pump

Large caliber submersible sewage pumpUsage conditions:
1. Medium temperature+40 ℃;
2. PH value 5-9;
3. The diameter of the largest solid particles can be between 25 and 50mm;
4. Submerged depth of 100m.
The flow range of this series of pumps is 50-500 cubic meters per hour, the head range is 40-110 meters, and the power is within 115 kilowatts. The rated voltage is 380V and the frequency is 50Hz.
Special occasions for use:
For situations where the water level changes significantly, that is, where the head amplitude varies greatly, this type of pump has the characteristic of safe use with full head and does not overload in both high and low flow areas.
★ Used in deep submergence situations, this type of pump can withstand a water pressure of 100m for safe use.
★ Used for low flow, high head sewage discharge occasions, especially suitable for long-distance transportation of sewage.
★ Suitable for occasions with high sediment content, this pump combines the characteristics of a slurry pump.
★ It has high reliability characteristics, especially suitable for major and key projects.


Large caliber submersible sewage pumpstructural characteristics

The design of deepwater high lift submersible sewage pumps reflects the requirement of high reliability everywhere.
Electric motor: Special insulation design ensures that the motor can still function normally in environments with minimal water ingress. The optimized design of the motor ensures that the water pump can start up in an environment where hydraulic components are partially submerged by sediment.
Hydraulic components: The design utilizes CFD and flow field diagnostic techniques, which have advantages such as high head, full head, high efficiency, no blockage, and wear resistance, and are at a high level. The project results have been applied for invention.
Sealing design: In order to meet the requirements of deep diving, multiple improvement measures have been adopted in the sealing of the water pump, including * sealing technology, which enables the water pump to operate at a depth of 100m underwater.
Protection measures: In addition to conventional motor protection, leakage detectors are also installed in the junction box chamber, motor chamber, and oil chamber. Two sets of stator overheating protection devices, one in use and one backup, are installed in the motor stator winding. A motor dehumidification device with * is installed in the motor to ensure stable insulation and prevent degradation.
